Innovative Cutting Edge

Three uniquely angled surfaces combine to form an innovative cutting edge designed to9:

  • Reduce insertion force
  • Minimize the need for pre-drilling

Traditional self-drilling / self-tapping screws have a straight tip vs CCHS/CSS+ angled tip. Angled cutting tips allow for efficient screw insertion into bone.

Features & Benefits

Cobalt Chrome Guide Wires

Cobalt Chrome Guide Wires 

Stiffer guide wire results in less deflection during screw insertion to maintain intended trajectory.10 

Trocar, threaded & fluted tip options available, depending on guide wire diameter.

MECHANICAL COMPARISON

CCHS & CSS+ vs. Competitors

The DePuy Synthes CCHS and CSS+ implants have a positive rake angle at their cutting tip, while generic compression screws feature a neutral rake angle. Their cutting tip differentiates the CCHS and CSS+ implants from generic compression screws and contributes to their superior cutting performance. 

This study demonstrates that DePuy Synthes CCHS and CSS+ have superior cutting performance when compared to Stryker Fixos/Fixos 2, Stryker Asnis Micro/Asnis III and Acumed Acutrak 2 Micro screws of comparable size when inserted into the same medium.13-15

Five cannulated compression screw systems were compared: DePuy Synthes CCHS and CSS+, Stryker Fixos/Fixos 2, and Stryker Asnis Micro/Asnis III and Acumed Acutrak 2 Micro. Screws were assigned to different test groups based on screw diameter: Group 1 contained 2.5 and 3.0 mm diameter screws, Group 2 included 4.0 mm screws and Group 3 was comprised of 6.5, 7.0 and 7.5 mm screws
